I'm not sure I totally agree with your definitions of the three kinds of courage: I believe physical courage occurs when a person actually uses physical contact in defending a person or belief, not the restraint of contact as your definition suggests. And I see little difference between your moral and emotional definitions of courage. Nevertheless, here are three quotes that relate to your three definitions of courage.

Moral.  Atticus displays a moral courage throughout the novel, but none is more evident than when he stands up to the lynch mob at the jail. Atticus stands alone against the men, who have made sure that Sheriff Tate won't be around.

     "Called 'em off on a snipe hunt... Didn't you think a'that, Mr. Finch?"
     "Thought about it, but didn't believe it. Well then," my father's voice was still the same, "that changes things, doesn't it?"
     "It do," another deep voice said...
     "Do you really think so?"  (Chapter 15)

Tate's absence doesn't alter the events for Atticus, who is willing to stand his ground on principle and risk his life for his client.

Emotional.  Scout displays this type of courage on occasion, especially when she grits her teeth, heeds Atticus's advice, and walks away from a fight with Cecil Jacobs.

     Somehow, if I fought Cecil Jacobs I would let Atticus down. Atticus so rarely asked Jem and me to do something for him, I could take being called a coward for him. I felt extremely noble for having remembered...  (Chapter 9)

Physical.  I believe Boo Radley displays the greatest physical courage in the novel, subduing Bob Ewell and killing him before he does away with Jem and Scout. But Atticus's standoff with Bob Ewell in town probably better fits your own definition of physical courage. When Bob curses Atticus, spits in his face, and calls him out for a fight, Atticus stands his ground much in the same way he does at the jail. According to Miss Stephanie,

... Atticus didn't bat an eye, just took out his handkerchief and wiped his face and stood there and let Mr. Ewell call him names wild horses could not bring her to repeat... Atticus's peaceful reaction probably prompted him [Bob] to inquire, "Too proud to fight, you nigger-lovin' bastard?"... Atticus said, "No, too old," put his hands in his pockets and strolled on.  (Chapter 23)
